| Description |
English: Calibration GIF of four differently coloured 64x48 pixel sized frames in groups of 1, making 4 frames in total displayed in four seconds. Each unique frame contains four coloured rectangles in a checkerboard pattern. Each subsequent frame comprises the previous frame's colours rotated 90 degrees clockwise.
English: This OGV file is intentionally made at 64 pixels wide by 48 pixels high and with a 4 bit colour palette in order to test media players. A correct media player with all post-processing disabled should play frames 1 to 25 over one second and then frames 26 to 50 for the next second and so on. Each coloured rectangle should appear completely black, completely white, completely red or completely green, and all edges should be sharp. |
